Question

finding the shape of a dot plot
number of classes
the dot plot shows the number of classes taken by the
students at south high school.
the shape of the data is
o skewed left.
o skewed right.
o symmetrical.
o from 3 to 7.

Explanation:

A symmetrical dot - plot has a balanced distribution of data points on either side of the center. In a skewed - left plot, there is a tail on the left side (fewer data points on the left). In a skewed - right plot, there is a tail on the right side (fewer data points on the right). "From 3 to 7" describes the range, not the shape. Looking at the dot - plot (assuming a balanced appearance as per the general concept of symmetry in such problems), we check the definitions.

Answer:

Symmetrical.
